We only processed around 300,000 - 400,000 messages per month on our FreeBSD box, but we didn't have any issues with ClamAV with Postfix and Amavisd-new on FreeBSD 6.1 (dual-AthlonMP with 4 GB RAM and 400 GB disk in RAID5). With one exception: getting an MFS to work for Amavisd's tmp directory. Worked for awhile, then it kept stalling mail delivery. Switching back to a disk-based tmp got things working, but slowed delivery down a bit. We also used CommandAV as a secondary AV tool until our license ran out (thank god -- CommandAV is a horrid piece of junk on any OS). After that, we used Kaspersky AV. The FreeBSD package doesn't follow hier(7) even the slightest, but it is a fast AV scanner and can be used as either a mail gateway daemon (including its own SMTP server) or as a scanner in amavisd-new. We've since moved our mail server over to a dual-Opteron setup with 4 GB RAM running Debian Etch (64-bit). More for political reasons than anything. Unfortunately, there's no 64-bit version of Kaspersky as of yet, so we're only using ClamAV on there (haven't felt like getting a 32-bit environment working on Debian). -- Freddie Cash fcash@ocis.net
